Objective To investigate the effectiveness of background music in operating room on psychology of patients and medical personnels. Methods A total of 127 patients who would receive selective operation and 65 surgical staff in our hospital were randomly divided into the intervention group and the control group. There were 63 patients and 30 medical personnel in the intervention group, 64 patients and 35 medical personnel in the control group. Routine care was given to all patients, and background music was broadcasted after patients and medical personnels coming into operating room in the intervention group. The blood pressure and heart rate of patients were contrasted, and the anxiety status was evaluated by Self-Rating Anxiety Scales (SAS), Visual Analogue Scale was used to appraise the horror, discomfort and pain between the control group and the intervention group. Results Diastolic pressure and systolic pressure was higher and heart rate was more rapid in the control group than in the intervention group. SAS score of patients and medical personnel was higher in the control group than in the intervention groups, degree of horror, pain and complaint in patients was more apparent in the control group than in the intervention group. Conclusions Background music could release negative emotion and was helpful for stabling the mood of medical personnel and preserving physical and mental health of patients.

Objective: To observe the clinical efficacy of heat-sensitive moxibustion for adjuvant treatment of depression in Parkinson disease and explore its mechanism. Methods: A total of 80 patients with Parkinson disease coupled with depression were randomized into an observation group and a control group, with 40 cases in each group. The control group was treated with levodopa and benserazide hydrochloride tablets and paroxetine tablets, while the observation group was treated with heat-sensitive moxibustion on the basis of the medications in the control group. The treatment course was 2 months. The Hamilton depression scale-17 (HAMD-17), unified Parkinson's disease rating scale (UPDRS) and Parkinson's disease quality of life questionnaire-39 (PDQ-39) were scored before and after the treatment, and the efficacy was evaluated after treatment. Levels of patients' serum dopamine (DA), 5-hydroxytryptamine (5-HT), tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) were detected before and after the treatment. Results: After treatment, the total effective rate of the observation group was higher than that of the control group (P<0.05). The HAMD-17 scores in the two groups decreased significantly after treatment (both P<0.05), and the score in the observation group was obviously lower than that in the control group (P<0.05). The component scores and total scores of UPDRS in both groups decreased significantly (all P<0.05), and the scores in the observation group were lower than those in the control group (all P<0.05). The score of PDQ-39 in the observation group decreased significantly (P<0.05), and was lower than that in the control group (P<0.05). After treatment, the serum DA and 5-HT levels in the observation group increased significantly (both P<0.05) and the TNF-α and IL-6 levels decreased significantly (both P<0.05), which were statistically different from those in the control group (all P<0.05). Conclusion: Heat-sensitive moxibustion has certain auxiliary effect in treating depression in Parkinson disease, significantly improving clinical symptoms and the quality of life, which may be related to the up-regulation of DA and 5-HT levels and down-regulation of TNF-α and IL-6 levels.

OBJECTIVETo investigate the expression of loricrin (LOR) and cytochrome P450 3A5 (CYP 3A5) in oral submucous fibrosis (OSF) and to evaluate their roles in the defending ability of epithelium mucosae.

METHODSThe expression of LOR and CYP 3A5 was examined in the specimens of 66 OSF and 14 normal buccal mucosa samples by immunohistochemistry, and the protein and mRNA expression of them was detected by Western blot and reverse transcriptase-PCR (RT-PCR).

RESULTSLOR was overexpressed in 42 (63.6%) cases of OSF, and showed a significant difference only between the early and moderately stages of OSF (P < 0.05), but no clear difference between moderately and advanced stages (P > 0.05). All normal buccal mucosa tissues showed positive immunoreactivity for CYP 3A5 protein in the membrane and cytoplasm of spinous epithelial cells and cytoplasm of endothelial cells, 5 (7.6%) cases of OSF showed weak staining of CYP 3A5 in spinous epithelial cells and 33 (50%) showed faint in cytoplasm of endothelial cells. A negative relationship between its expression and pathological stages was found in OSF (P < 0.05). RT-PCR results were fully consistent with the immunohistochemical data. But the results of Western blot only showed the expression of CYP 3A5 was significantly higher in normal buccal mucosa samples than OSF.

CONCLUSIONThe results suggest that the LOR and CYP 3A5 might play a vital role in the change of defending ability of epithelium mucosae as well as the pathopoiesis and carcinogenesis of OSF.

OBJECTIVETo seek effective drugs for anti-hepatitis C virus by screening 20 Chinese herbs often used for clearing heat and dissipating toxin with nude mice model of hepatitis C viral (HCV) infection.

METHODSAfter the model mice had been treated with selected drug for 3 months, transmission electron microscope was used to observe whether the HCV-like particles in human fetal hepatocytes (HFH) transplanted into mice spleen still existed, and quantitative RT-PRC technique was used to detect the serum content of HCV-RNA before and after treatment.

RESULTS(1)HCV-like particles existed in all the model mice after treatment. (2) Serum content of HCV-RNA decreased after treated with Radix Gentianae, Radix Scutellariae, Radix Sophorae tonkinensis, Fructus Gardeniae and Fructus Sophorae flavoscentis, but unchanged after treatment with other drugs.

CONCLUSIONAll the 20 herbs screened has not effect in directly eradicating HCV, but Radix Gentianae, Radix Scutellariae, Radix Sophorae tonkinensis, Fructus Gardeniae and Fructus Sophorae flavoscentis could significantly inhibit the replication of HCV-RNA.

OBJECTIVETo observe the changes of electrocardiogram (ECG) and pregnancy outcome of the late pregnancy women.

METHODSLate pregnancy women were divided into two groups by age: over 35 group and under 35 group. The incidence of abnormal electrocardiogram was recorded when the patients were subjected to routine ECG examination. Then the pregnancy, delivery outcome and if there's low birth weight newborn were recorded later.

RESULTSThe incidence of abnormal ECG in over 35 group was significantly higher than that in under 35 group (P < 0.05). And the incidence of ST segment changes, arrhythmia in the group of former was higher than that in the group of latter (P < 0.05). Among the different type of arrhythmia, the incidence of sinus bradycardia and ventricular premature beat in the group of former were higher than those in the group of latter (P < 0.05). But the incidence of sinus tachycardia in the former group was obviously lower than that in the latter group (P < 0.05). The incidence of pregnancy loss in over 35 with abnormal ECG group was significantly higher than that in under 35 with normal or abnormal ECG groups (P < 0.05). The incidence of premature birth in over 35 with abnormal ECG group was significantly higher than that in over 35 with normal ECG group (P < 0.05). The incidence of low body weight in over 35 with abnormal ECG group was significantly higher than that in under 35 with normal ECG group (P < 0.05).

CONCLUSIONThe late pregnancy women with the age of over 35 are more likely to have ECG abnormalities, such as arrhythmia, myocardial ischemia and so on. The older pregnant women with abnormal ECG easily suffer from pregnancy losing, premature birth and having a low birth weight baby.

Objective To observe the influence of exterior-interior meridian acupoint selection on hippocampal cell apoptosis and c-Jun N-terminal kinase ( JNK) in ischemia-reperfusion injury rats, and to explore the possible protective mechanism for ischemia-reperfusion injury. Methods One hundred and twenty SD rats were randomly divided into sham-operation group (SH), model group (I/R), electroacupuncture (EA) group and JNK inhibitor SP600125 ( SP) group. The ischemia-reperfusion model was established by occlusion of middle cerebral artery with intraluminal thread. EA group was given EA on acupoints of Zusanli ( ST 36) , Sanyinjiao ( SP 6) , Chize ( LU 5) , Hegu ( LI 4) , once a day, based on the method of exterior-interior meridian acupoint selection. We observed the neurological behavioral changes by Longa neurological function standard, detected the activation of phosphorylated JNK ( p-JNK) by immunohistochemical method and examined the hippocampal apoptotic index by TUNEL method. Results The neurologic impairment scores of EA group and SP group were lower than I/R group (P<0.05) . Apoptotic index of I/R group was higher than SH group (P<0.01) and that of EA group and SP group was lower than I/R group (P <0.05) . The level of p-JNK in I/R group was higher than SH group ( P <0.01) and that of EA group and SP group was lower than I/R group ( P <0.05). Conclusion Exterior-interior meridian acupoint selection therapy has certain effect on alleviating neurologic impairment and reducing apoptosis in ischemia- reperfusion injury rats, and the mechanism might be associated with the inhibition of the activation of JNK signaling pathway.

AIM:To study the visual acuity and refractive status of students pupils and middle school students in Shenzhen, and to provide a scientific basis for the prevention and control of myopia.
METHODS:A cluster sampling method was used to select five primary school students(6 737) and three junior middle school students(1 925) from Shenzhen. The visual acuity, anterior segment, fundus, eye position, and refractive status were measured. Information on associated factors for poor vision were also obtained using a questionaire. The risk factors of poor vision and the rate of myopia between grade or gender were analysed by Chi-square test.
RESULTS:The rate of poor vision was 67. 0%. Female, family history of high myopia, long time of continuous look near, short time of outdoor activities were the main risk factors. The rate of emmetropia, hyperopia, astigmatism and myopia were 15. 1%, 11. 3%, 11. 0% and 62. 6% respectively. Emmetropia, hyperopia and astigmatism incidenece rate decreased with age growing, but myopia incidence rate was increased. There were significant differences between adjacent two grades in myopia(χ2=7. 338-45. 018, P<0. 05 ) except the primary grade six and the junior grade one. There were significant differences between boys ( 61. 0%) and girls ( 65. 5%) in myopia(χ2=17. 180, P<0. 05).
CONCLUSION:The rate of poor vison is pretty high in students of Shenzhen aged between 5 to 16 years old, and myopia is the main reason. The development rate of myopia is increased with age. Early management of myopia may play an important role in controlling poor vision in students.
